A Quality Improvement Initiative to Reduce Abdominal X-ray use in Pediatric Patients Presenting with Constipation.

Objective: To decrease the percentage of patients undergoing an abdominal radiograph for evaluation of constipation within 24 hours of their initial gastroenterology visit.

Study Design: In January 2015, we implemented a quality improvement, evidence-based guideline (EBG) aimed at standardizing the initial assessment of patients presenting for a new outpatient gastroenterology visit with a primary complaint of constipation. Over the subsequent 5 years, we followed the clinical impact of this guideline initiation with the goal of decreasing unnecessary abdominal radiograph use by 10% within 1 year of EBG launch.

A rapid, parasite-dependent cellular response to Dirofilaria immitis in the Mongolian jird (Meriones unguiculatus).

Background: The Mongolian jird (Meriones unguiculatus) has long been recognized as a permissive host for the filarial parasite Brugia malayi; however, it is nonpermissive to another filarial parasite, canine heartworm (Dirofilaria immitis). By elucidating differences in the early response to infection, we sought to identify mechanisms involved in the species-specific clearance of these parasites. We hypothesized that the early clearance of D.

AVPR1A distribution in the whole C57BL/6J mouse neonate.

The neuropeptide arginine vasopressin (AVP) plays significant roles in maintaining homeostasis and regulating social behavior. In vaginally delivered neonates, a surge of AVP is released into the bloodstream at levels exceeding release during life-threatening conditions such as hemorrhagic shock. It is currently unknown where the potential sites of action are in the neonate for these robust levels of circulating AVP at birth.

Efficacy and side effects of doxycycline versus minocycline in the three-dose melarsomine canine adulticidal heartworm treatment protocol.

Background: The American Heartworm Society currently recommends the use of a monthly macrocyclic lactone, a 28-day course of 10 mg/kg doxycycline BID, and the 3-dose protocol of melarsomine dihydrochloride for the treatment of canine heartworm disease. Doxycycline is necessary for the reduction of the bacterium Wolbachia, found in all heartworm life-stages. Previous price increases and decreasing availability prompted us to evaluate alternative tetracycline antibiotics, i.

The role of adenovirus-mediated retinoblastoma 94 in the treatment of head and neck cancer.

A truncated retinoblastoma (RB) protein of approximately 94 kDa (RB94), lacking the NH2 -terminal 112 amino acid residues of the full-length RB, has been found to have great efficacy in tumor suppression. This study investigated the role of adenovirus-mediated RB94 (Ad-RB94) gene therapy for human head and neck squamous cell carcinoma (HNSCC) and explored the cellular and molecular mechanism of tumor inhibition after Ad-RB94 gene transfer. Randomized controlled studies in vitro and in vivo were performed to assess antitumor responses of Ad-RB94 gene transfer against human HNSCC.
